WebAssembly (WASM): The New Frontier of Web Development
Hello HaWkers! Today we're going to talk about WebAssembly, an innovative technology that is revolutionizing web development.
What is WebAssembly?
WebAssembly (WASM) is a binary code format that allows low-level languages such as C++, Rust, and Go to run in the browser. This opens up a new world of possibilities for web application development, enabling the creation of high-performance applications that were previously unfeasible in the browser environment.
Why use WebAssembly?
WebAssembly is a technology that has the potential to transform the web. Here are some reasons to consider using WASM in your projects:
- Performance: WASM is compiled, which means it is much faster than JavaScript.
- Portability: WASM can be run on any platform that has a compatible browser.
- Low-level languages: With WASM, you can write code for the web in low-level languages like C++ and Rust.
Code Example
Here is an example of how a WASM module can be loaded and used in JavaScript:
fetch('my_module.wasm') .then(response => response.arrayBuffer()) .then(bytes => WebAssembly.instantiate(bytes)) .then(results => { // 'results' is an object that contains both the instantiated WASM module and its instances. const { instance } = results; const result = instance.exports.minhaFuncaoExportada(); console.log(result); // print the result of the WASM function });In the code above, we are searching for a WASM module, transforming the response into an ArrayBuffer, instantiating the WASM module, and then using one of the functions exported by the module.
WebAssembly is an emerging technology that is gaining more and more prominence in web development. If you're a web developer and want to be on the cutting edge of technology, WASM is worth taking a look at.
